Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention is mainly concerned with a feeding device for food, and more particularly, it is a feeding device for food products, and more specifically, it is a feeding device for food products, and more specifically, for feeding ingredients such as shumai, gyoza, etc., cream, jam, bean paste, etc., which are fed into a hopper above a filling machine. This invention relates to a feeding device suitable for smoothly feeding a so-called paste product to a filling machine below.

B. Prior Art Conventionally, in this type of hopper, as a means for sending the input material to the filling machine connected below the hopper, a screw was suspended in the center of the hopper, and the screw was driven by a rotary drive connected above. A method was adopted in which the material inside the hopper was forcibly sent downward while being rotated by a mechanism.

C. Problems to be Solved by the Invention However, such a screw system has various drawbacks as described below.

That is, since the rotational force of the screw is used, the input materials tend to overflow, and there is a risk that the materials will be kneaded in more than necessary.

As a result, for example, if the input ingredients are ingredients such as shumai or gyoza, the moisture (juice) contained in the ingredients
The problem was that it dripped and the taste deteriorated.

In addition, only the input material located at the center of the hopper is fed to the filling machine below, and the outer portion tends to remain in the hopper.

Furthermore, there is a drawback that the materials contained in the input materials, such as the vegetables contained in the ingredients, the chopped pieces of fruit contained in the cream, jam, etc., or the green peas contained in the green peas, etc., are crushed or crushed.

The present invention has been made in view of the above-mentioned drawbacks, and is a feeding device that can push out the material as it is with the palm of the hand without kneading the material fed into the hopper and send it to the supply port below. It provides:

D. Means for solving the above-mentioned problems The means of the present invention for achieving the above-mentioned object is to suspend a shaft connected to an elevating mechanism above the outlet in the lower part of the hopper so as to be able to move up and down, and to attach the shaft to the inside of the hopper. It is equipped with a hinge-type pushing piece that can be opened and closed to send out the objects to the lower delivery port.

E. Effect: Inject the object 2 into the hopper 1, for example,
When the gyoza tool is put in and the rod 7a of the air cylinder 7 as a lifting mechanism is lowered, the shaft 4
Both menisci 3a, 3a of the pushing piece 3, which is in the closed state as shown by the solid line in FIG. 2 toward the outlet 1a.

At this time, both menisci 3a, 3a are locked and fixed to the lower edge of the shaft 4 in a state of opening approximately 90 degrees as shown by the dashed line in FIG. .

Next, when the rod 7a of the air cylinder 7 is raised, both menisci 3a, 3a of the pushing piece 3, which is in the open state as described above, are smoothly closed using the pin 10 as a fulcrum due to the resistance of the transported object 2, and are smoothly moved into a predetermined position. rise to position.

In this state, the shaft 4 descends again, and the same operation is repeated automatically and continuously.

Further, as shown in FIGS. 5 and 6, the structure in which two pushing pieces 13, 13 are attached to the upper and lower sides of the shaft 4 is similar to the above.

That is, as the rod 7a descends, each pushing piece 1
The rectangular plates 13a and 13a of 3 and 13 are simultaneously opened with the pin 10 as a fulcrum, and the object 2 in the hopper 1 is
is sent out toward the delivery port 1a using two pushing pieces 13, 13.

Next, as the rod 7a rises, the upper and lower rectangular plates 13a, 13a close simultaneously and smoothly rise to a predetermined position.

Thereafter, similar operations are repeated.

F. Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Figures 1 to 4 show a first example of implementing the present invention, in which the hopper 1 is made of a material that does not have a chemical effect on the objects 2 to be sent, such as ingredients for shumai or gyoza, for example, the inner surface is coated with Teflon. A shaft 4, on which a hinge-type pushing piece 3 is attached so as to be openable and closable, is vertically suspended in the upper center of the outlet 1a, which is formed of a stainless steel plate and has an inverted conical shape and is open at the lower center.

5 is a filling machine connected to the lower part of the hopper 1, and its internal mechanism (not shown) is connected to the delivery port 1.
It is connected to a.

The shaft 4 suspended above the outlet 1a of the hopper 1 is connected to the support arm 6 above.
The lower end of the rod 7a of the air cylinder 7 is connected to the lower end of the air cylinder 7 by a coupling 8 as an elevating mechanism supported perpendicularly to the air cylinder 7.

Further, a connecting pipe 9 for attaching the pushing piece 3 to the lower end of the shaft 4 is integrally held and fixed in a horizontal state in a notch thereof.

As shown in FIG. 3, the pushing piece 3 has a circular shape when opened, and the connecting tubes 3b, 3b are located inside the two meniscuses 3a, 3a, and the connecting tube 9 of the shaft 4 is located in the center. The connecting pipes 3b, 3b and the connecting pipe 9 are arranged in a straight line and a long pin 10 is inserted into each pipe. It is hinged to the lower end of the shaft 4 so as to be openable and closable.

Therefore, the rod 7a of the air cylinder 7
When the hopper is lowered, both menisci 3a, 3a of the pushing piece 3 attached to the lower end of the shaft 4 change from the state shown by the solid line in FIG. Open as shown. At this time, the opening angle of the pushing piece 3 stops at 90 degrees as shown in the figure, as each meniscus 3a is engaged with the lower end line 4a of the shaft 4.

Next, when the rod 7a of the air cylinder 7 rises, both menisci 3a, 3a of the pushing piece 3 move against the object 2.
Due to the resistance in the opposite direction to the above, the state returns to the state shown by the solid line in FIG. 4 and closes.

Note that a spring (not shown) may be used to smoothly open and close the pushing piece 3.

In addition, the lifting speed of the rod 7a of the air cylinder 7 can be automatically controlled according to the viscosity and amount of the object 2 to be transported. Although this hole is for reducing the resistance of No. 2, a plurality of notches (not shown) may be provided on the outer edge.

Next, FIGS. 5 to 10 show a second example of carrying out the present invention, in which a connecting pipe 9 is held and fixed to the lower end of the shaft 4, and a connecting pipe 12 is also attached to the substantially interrupted portion of the shaft 4 above the connecting pipe 9. is fixed through the connecting pipes 9 and 12, and pushing pieces 13 and 13 are respectively attached to both connecting pipes 9 and 12 in two stages.

The pushing pieces 13, 13 are arranged so that the connecting pipes 9 or 12 of the shaft 4 are located inside the two rectangular plates 13a, 13a, with the connecting pipes 13b, 13b in the center, as shown in FIGS. They are integrally formed at predetermined intervals, and each connecting pipe 13b,
13b and the connecting tube 9 or 12 are arranged in a straight line, and by inserting a long pin 10 into each tube, the shaft 4 is hingedly held at the lower end of the shaft 4 and above it so as to be openable and closable.

As a result, the respective pushing pieces 13, 13 are opened and closed by the resistance of the object 2 thrown into the hopper, as in the first embodiment. Further, in this embodiment, a plurality of notches 14 are provided at the outer edge of each rectangular plate 13a, 13a in order to reduce the resistance of the object 2, but holes may be made as in the first embodiment. .

In addition, in the figure, 15 is a notch for penetrating the shaft 4 provided at the center inside of the rectangular plates 13a, 13a attached to the middle side of the shaft 4, and 15 is a notch for passing through the upper pushing piece 1.
3 is a stop protrusion provided on the shaft 4 to prevent it from opening more than 90 degrees, and 17 is a notch into which the tip of the pushing piece 13 enters when closed.

By the way, in the above embodiments, the number of pushing pieces 3, 13 is up to two, and the shapes are only circular and rectangular, but it is needless to say that they are not limited to these.
It can be changed at any time depending on the size and shape of the hopper 1.

Effects of the Invention As described above, in the feeding device according to the present invention, the shaft 4 connected to the lifting mechanism 5 is suspended above the delivery port 1a below the hopper 1 so as to be able to rise and fall freely, and the The conveyed object 2 is sent to the lower outlet 1.
Hinge-type pushing pieces 3 and 1 sent out toward a
3 is attached so that it can be opened and closed freely, and when the shaft 4 descends, each pushing piece 3, 13 automatically opens due to the resistance of the object 2, and when the shaft 4 rises, each pushing piece 3, 13 opens automatically. Since it is designed to close automatically due to the resistance of object 2, the movement of the shaft 4 to rise is extremely smooth, and the structure is simple, reducing not only product cost but also power cost. .

Moreover, each pushing piece 3, 13 does not rotate,
Since the object 2 is sent out linearly as if it were pressed with the palm of a hand, there are problems caused by kneading the object 2 more than necessary, for example, the moisture (juice) contained in the object 2 drips and deteriorates the taste. falls or
This completely eliminates drawbacks such as crushing or grinding of granular solids.
